A method and device for sampling a fragment of tissue in which a contrast medium is injected into an organ to be examined and highlights parts containing that contrast medium in an image obtained by emitting a beam of X-rays. Polytetrafluoroethylene film is suited as material for the band. The pedals are connected to the jackshaft through a chain or belt and a jackshaft-pedal freewheel which allows the pedals to drive the jackshaft, but prevents the jackshaft from driving the pedal. The band includes a male end which fits into a female end in a zip-tie like manner. Thru-holes are also possible, albeit not required. A device can place a telephone call to an Integrated Device via dialing on the PSTN and have the call consummated over the Internet via a mechanism of messaging between the associated devices and systems.
